First, gather the data to be exported. Next, format the data into a CSV string by joining values with commas and rows with line breaks. Utilize the Blob API or FileSaver library to create and download the CSV file.

How can I export data to a CSV file or Excel in Reactjs?
This Reactjs code exports data to a CSV file (Excel). It defines a functional component 'App' that holds sample CSV data. When the 'Export Data to CSV file' button is clicked, the 'generateCSV' function is triggered. It converts the data into CSV format and creates a download link. When the link is clicked, the CSV file is downloaded. This enables users to export the provided data in a CSV file format for further use or analysis.

How can I use Reactjs to create a CSV file based on user input and then export the data to an Excel file?
This ReactJS script creates a web application that allows users to input data (name, email, and role) into fields. When the "Add Data" button is clicked, the data is stored in memory. Upon clicking the "Generate CSV" button, the stored data is converted to CSV format and exported as a downloadable file named "data.csv." The script also includes a simple toast notification system to display success or error messages to the user.
